The fields are no longer being overwritten
I am running version 17 since yesterday and I notice one very annoying thing that didn't happen in version 16 and before.
When I go to a login page that contains a username field and a password field and the username field is already filled in, usually when I click "Auto-complete form" in the Top Bar of PD it would overwrite whatever was filled in inside that field.
Now it adds it to whatever was already filled in.
Username field: Martin
I click Autocomplete form and then click inside the Username field the result would be MartinMartin.
Username field: MartinMartin
Password field: 1234
In the past the content of the Username field would be overwritten.
